TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors and windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool indoor air quickly, in a short period of time.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block
the air flow or weaken the cooling / dehumidifying functions.

Preparing for operation
• Contact an installation specialist for installation.
• Use a dedicated circuit.
Usage
• Being exposed to direct airflow for an extended period of time could be hazardous to your
health. Do not expose occupants, pets, or plants to direct airflow for extended period of time.
• Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves
or other heating devices.
• Do not use this air conditioner for non-specified special purposes (e.g. preserving precision
devices, food, pets, plants, and art objects). Such usage could damage the items.
Cleaning and maintenance
• Do not touch the metal parts of the unit when removing the filter. Injuries can occur when
handling sharp metal edges.
• Do not use water to clean inside the air conditioner. Exposure to water can destroy the
insulation, leading to possible electric shock.
• When cleaning the unit, first make sure that the power and breaker are turned off. The fan
rotates at a very high speed during operation. There is a possibility of injury if the unit’s power
is accidentally triggered on while cleaning inner parts of the unit.

Operation Tips
Do not overcool the room.
This is not good for the health
and wastes electricity.
Keep blinds or curtains closed.
Do not let direct sunshine
enter the room when the air
conditioner is in operation.
Keep the room temperature
uniform.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and
windows as much as possible
to keep the cool air in the
room.
Clean the air filter regularly.
Blockages in the air filter
reduces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once
every two weeks.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.
When air conditioner is not going
to be used for a long time.
1Operate the air conditioner at the following
settings for 2 to 3 hours.
- Type of operation: Fan operation mode.
- This will dry out the internal mechanisms.
Helpful information
The air filters and your electric bill.
If the air filters become clogged with dust, the
cooling capacity will drop, and 6 % of the
electricity used to operate the air conditioner
will be wasted.
When the air conditioner is to be
used again.
1Clean the air filter and install it in the
indoor unit.
2Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
3Check that the ground wire is connected
correctly. It may be connect to the indoor
unit side.
Turn off the breaker when the air
conditioner is not going to be used for a
long time.
Dirt may collect and may cause a fire.
CAUTION

MAINTENANCE AND SERVICE
ENGLISH
19
Call the service immediately in the following situations
1Anything abnormal such as burning smell, loud noise etc. happen. Stop the unit and turn the
breaker off. Never try to repair by yourself or restart the system in such cases.
2Main power cord is too hot or damaged.
3Error code is generated by self diagnosis.
4Water leaks from indoor unit even if the humidity is low.
5Any switch, breaker (safety, earth) or fuse fails to work properly.
User must carry routine checkup & cleaning to avoid unit’s poor performance.
In case of special situation, the job must be carried out by service person only.
The air conditioner does
not operate.
- Have you made a
mistake in timer
operation?
- Has the fuse blown or
has the circuit breaker
been tripped?
The room has a peculiar
odor.
- Check that this is not a
damp smell exuded by
the walls, carpet,
furniture or cloth items
in the room.
It seems that
condensation is leaking
from the air conditioner.
- Condensation occurs
when the airflow from
the air conditioner
cools the warm room
air.
Air conditioner does not
operate for about 3
minutes when restart.
- This is the protector of
the mechanism.
- Wait about three
minutes and operation
will begin.
Does not cool
effectively.
- Is the air filter dirty?
See air filter cleaning
instructions.
- The room may have
been very hot when
the room air
conditioner was first
turned on. Allow time
for it to cool down.
- Has the temperature
been set incorrectly?
- Are the indoor unit's
air inlet or outlet vents
obstructed?
The air conditioner
operation is noisy.
- For a noise that
sounds like water
flowing.
* This is the sound of
freon flowing inside
the air conditioner
unit.
- For a noise that
sounds like the
compressed air
releasing into
atmosphere.
- This is the sound of
the dehumidifying
water being processed
inside the air
conditioning unit.
Crack sound is heard.
- This sound is
generated by the
expansion/constriction
of the front panel, etc.
due to changes of
temperature.
Remote control display
is faint, or no display at
all.
- Are the batteries
depleted?
- Are the batteries
inserted in the
opposite (+) and (-)
directions?
The air conditioner
changes generated
airflow during operation.
When the air
conditioner reaches the
desired temperature,
the airflow rate reduces
in order to avoid
generating cool airflow
during heating, or to
minimize energy
consumption and indoor
humidity change during
cooling.
- This symptom is
normal.
The error code is
occurred after lightning
struck
- This product has been
applied to the over
current protection
circuit.
Error can occur, but it
is normal behavior.
After few minutes, It
will operate normally.
